emerge of kdenetwork fails, referencing the need for qt to be compiled with opengl to support Video4Linux webcams. v4l USE flag is not set - does the kdenetwork ebuild check for it? Error message appears different to other bugs filed relating to qt and opengl.

try USE="opengl" emerge -1 =x11-libs/qt-3* This worked for me
Thanks gamf - I don't doubt that would work, but its a work-around, not a fix. It shouldn't be necessary to enable a USE flag I don't want (opengl), to get a feature I don't need (v4l webcam support), just so that kdenetwork will compile.
Upstream does not give us a way to disable that. If you don't want it, use kdenetwork-meta and not merge kopete. If you want you can submit a bug for it on bugs.kde.org and see if mattr is going to finally make some things configurable.
